System and Method for Incorporating and Releasing a Substance into a Smokable Material

ABSTRACT

A system and method for incorporating and releasing a substance into a smokable material is provided. In one embodiment of the present invention, a smokable element (e.g., a cigarette) includes a first wrapper and a filler (e.g., tobacco,  cannabis , etc.) encased by the first wrapper. A capsule is then embedded within the filler and a second wrapper is placed over the first wrapper adjacent the capsule. The capsule may comprise a liquid (e.g., cannabinoids, terpenes, etc.) encased within a shell. By squeezing the second wrapper, the shell can be crushed (or broken open), releasing the liquid into the filler, thereby creating a “splash zone.” Vapors and/or smoke from the splash zone can then be inhaled by a user, enhancing the user&#39;s smoking experience.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to manufacturing and using a smokable element (e.g., cigarette, etc.), and more particularly to an element that includes a filler and at least one capsule containing a substance (e.g., liquid, etc.), wherein the substance can be released into the element (e.g., by crushing the capsule, etc.), allowing the substance to be inhaled and/or smoked by the user, preferably during combustion of the element or a portion thereof.

2. Description of Related Art

Smokable elements, like cigarettes, exist in all different shapes, sizes, and varieties. For example, while Marlboro™ offers a standard-length cigarette referred to as Reds, they also offer a shorter version referred to as 72's. And while Reds are considered a “full flavored” cigarette, Marlboro also offers lighter versions, such as Golds and Silvers. They also offer different flavors, such as Southern Cut, which is a sweeter blend, Menthols, their standard mentholated version, and Smooths, a menthol variation. In fact, Marlboro™ currently offers 43 different varieties of cigarettes for sale in the United States. While variety is generally a good thing, it usually requires a consumer to make a decision at a time of purchase, which may differ from what the consumer desires at a time of consumption.

In an effort to address this, Marlboro™ introduced its NXT cigarette, which is a regular cigarette that has a fluid-filled bead located in the filter. By squeezing the filter, the bead is popped, and a mentholated substance is dispersed into the filter, thereby adding a menthol taste to each inhalation of smoke. Thus, if the user desires a regular cigarette, the bead is left in unbroken. Alternatively, if the user desires a menthol taste, either before or after the cigarette is lit, the user merely squeezes the filter, thereby releasing the mentholated substance into the filter.

While this is a step in the right direction, there are several drawbacks with this solution. First, by dispersing a mentholated substance into the filter, only menthol vapors (or vapors resembling menthol) are inhaled. This is in contradistinction to a menthol cigarette, where smoke from menthol flavored tobacco is inhaled. And because only vapor is inhaled, it limits the types of substances that can be included in the bead. For example, a psychoactive substance, such as liquid nicotine, that is intended to be ingested (e.g., smoked, etc.) would be ineffective if dispersed inside a filter. So too would other substances that do not put off vapors or whose vapors are an ineffective delivery mechanism. Finally, with other smokable elements becoming more popular (e.g., marijuana cigarettes, e-cigarettes, etc.), such a solution may be not be a viable option since many of these elements do not use or include a filter.

Thus, it would be advantageous to develop a system and method for incorporating and releasing a substance into a smokable portion of a cigarette, allowing the substance itself to be smoked. Such a system and method, however, would have to overcome certain drawbacks. For example, if the substance is too thick, it may not get dispersed throughout the smokable material. And if the substance is too thin, it may affect the integrity of the cigarette (e.g., the wrapper may become moist and fall apart, etc.). Moreover, liquid in the smokable region may affect the passage (or flow) of smoke to the user, or the burn-rate of the cigarette, which can affect both enjoyability and functionality. Thus, not only is the type of substance (including its viscosity) important, but so too is how the substance is dispersed (e.g., rate, direction, etc.). By way of another example, the smokable material (and the wrapper containing the same) must be resilient or at least maintain its integrity, even when inward pressure is required to release the substance.

It would therefore be advantageous to incorporate a substance into a smokable material that overcomes at least some of the foregoing drawbacks and does so in a manner that does not detract (or minimizes detraction) from enjoying the cigarette if the substance is not released.

SUMMARY OF THE INVENTION

The present invention provides a system and method for incorporating and releasing a substance into a smokable medium. Preferred embodiments of the present invention include a cigarette (construed broadly to include traditional cigarettes, cigars, joints, blunts, etc.) that comprises at least one filler, at least one wrapper, and at least one substance that is (or can be) released into the cigarette, allowing the user to inhale and/or smoke the substance, preferably during combustion of the cigarette, or a portion thereof.

In a first embodiment of the present invention, the cigarette includes a first wrapper and a filler, where the first wrapper encases the filler (forming a relatively cylindrical shape). The cigarette also includes a capsule embedded within the filler and a second wrapper that is located over the first wrapper and adjacent (i.e., surrounding) the capsule. Preferably, the capsule contains an outer shell and an inner liquid (within the shell), where the liquid can be released into the filler by crushing (or snapping) the shell. This may be accomplished by pressing inward on the second wrapper (e.g., via the thumb and forefinger), thereby crushing or snapping the shell, allowing release of the liquid. The liquid would then coat or cover the surrounding filler, creating a laced version of the filler, referred to herein as the “splash zone.”

For example, assume the filler is cannabis having a first level of THC and the liquid includes (at least in part) a cannabinoid oil having a second level of THC. By crushing the capsule and releasing the liquid, the cannabinoid oil would flow or seep into and over the surrounding cannabis, resulting in a “splash zone” having a higher THC level than that of the cannabis itself. This would allow a user to “boost” the level of THC that is ingested by merely pressing inward on the second wrapper, thereby crushing the capsule and releasing the liquid into the filler. In one embodiment of the present invention, the second wrapper is shorter than the first wrapper, thereby providing structural functionality where needed, without increasing the overall thickness of the cigarette, or the wrapper portion thereof.

It should be appreciated that the liquid inside the capsule is not limited to any particular liquid, and may include any fluid, such as liquid nicotine, cannabinoids (e.g., tetrahydrocannabinol (THC), cannabidiol (CBD), cannabinol (CBN), cannabigerol (CBG), etc.), terpenoids (e.g., pinene, myrcene, limonene, caryophyllene, linalool, humulene, ocimene, terpinolene, citrulline, etc.), flavonoids (e.g., flavonols, such as those naturally found in apples, tomatoes, etc., flavan-3-ols, such as those found in bananas, blueberries, etc., flavones, such as those found in parsley, oranges, etc., flavonones, such as those found in grapefruit, lemons, etc., and anthocyanidins, such as those found in strawberries, cherries, etc.), and/or other fluids (or semi-fluids) generally known to those skilled in the art, regardless of how the liquid is obtained (e.g., herbal distillation, etc.), or what it is obtained from (e.g., plants, flowers, herbs, etc.). The fluid should preferable increase, alter, or supplement the effects (e.g., the high, etc.), flavor, taste, smell, medicinal value, and/or enjoyability of the cigarette. While the present invention is not limited to any particular fluid (or for that matter, the use of fluid at all), because we are dealing with a smokable element, the liquid, or properties thereof (e.g., THC, CBD, CBG, terpenoids, flavonoids, etc.) are ingested by inhaling vapors from the splash zone (i.e., liquid-coated filler) and/or smoke from a combustion thereof. In other words, certain liquids will put off vapors once the liquid is exposed to air (hence one reason for encapsulating the liquid until it is ready to be used). For these liquids, the flow of smoke (or vapor in the case of an e-cigarette) over the splash zone is sufficient to ingest its properties. For other liquids, ingestion results from smoking, or inhaling the smoke produced during combustion of the splash zone.

It should be appreciated that for some liquid, ingestion is a combination of the two. Thus, by placing the splash zone near the user's mouth, the user will inhale vapors from the splash zone while the user is smoking the filler. These vapors may contain certain terpenes or flavonoids, thereby enhancing the user's smoking experience. Once the combustion reaches the splash zone, smoke resulting therefrom may contain certain cannabinoids (e.g., THC, CBD, CBG, etc.), thereby enhancing (or boosting) the effects (e.g., the high, medicinal value, etc.) of the cigarette.

In certain embodiments of the present invention, the cigarette may include features commonly found on traditional cigarettes, including a filter and/or a tip (for placement in the user's mouth). For example, the cigarette may include a tip, where the capsule is placed in the filler (as previously discussed), the cigarette may include a filter, where the capsule is placed in either the filler or the filter, or the cigarette may include both a tip and a filter, where the capsule is placed in either the filler or the filter. As discussed in greater detail below, the cigarette may also include a chamber (e.g., adjacent the filler, between the filler and the filter, between the filler and the tip, etc.), where the capsule is place in the chamber.

In a second embodiment of the present invention, the cigarette may be both cylindrical and tapered, where the diameter of the cigarette increases from a proximal end to a distal end. As with other embodiments, the capsule may be placed inside the filler, allowing a crushed (or snapped) capsule to create a splash zone within the filler. Vapor from the splash zone can then be inhaled and/or the splash zone can be smoked, as previously discussed. Those skilled in the art will understand that there are certain benefits to this “tapered” shape (placing a larger amount of smokable material up-wind, toward the distal end, and a smaller amount of smokable material down-wind, toward the proximal end).

A more complete understanding of a system and method for manufacturing and using a smokable element will be afforded to those skilled in the art, as well as a realization of additional advantages and objects thereof, by a consideration of the following detailed description of the preferred embodiment. Reference will be made to the appended sheets of drawings, which will first be described briefly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Preferred embodiments of the present invention include a cigarette that comprises at least one filler, at least one wrapper, and at least one substance that is (or can be) released into the cigarette, allowing the user to inhale and/or smoke the substance, preferably during combustion of the cigarette, or a portion thereof. It should be appreciated that the term “cigarette” is used herein in its broadest sense and includes any narrow cylinder (or other shape) containing a material or substance that can be smoked or inhaled, including a traditional cigarette, cigar, joint, blunt, spiff, jay, or doobie, or any electric version thereof. The term “filler” is also used in its broadest sense and includes all smokable material generally known to those skilled in the art, including tobacco, cannabis, and/or any other dried, smokable herb (cloves, etc.). Similarly, the term “wrapper” is used herein in its broadest sense and includes all smokable encasements (e.g., leaves, papers, etc.) generally known to those skilled in the art, including tobacco, cannabis, hemp, flax, sisal, rice straw, esparto, and/or other non-wood plant fibers. It should be appreciated that fillers and wrappers that include other substances (e.g., wrappers that include sodium potassium tartrate to regulate combustion, fillers that include added nicotine (or other psychoactive substances, such as THC) to increase its potency, etc.) are within the scope of the present invention.

In a first embodiment of the present invention, as shown in FIGS. 2A-D, a cigarette 100 includes a first wrapper 110 and a filler 140, where the first wrapper 110 encases the filler 140 (forming a relatively cylindrical shape), has a distal end 102, and has a proximal end 104. As shown in FIG. 3, the proximal end 104 is configured to be placed between the user's lips (see, e.g., 310) and the distal end 103 is configured to be lit by an external source 320. Once the distal end is lit, resulting in combustion of the filler 140 adjacent the distal end 102, inhalation by the user 310 (creating a vacuum) results in air being drawn from the distal end 102 toward the proximal end 104 (illustrated by arrow 330), allowing smoke from the combustion to be inhaled by the user 310. Depending on the type of filler, the smoke will have a different effect on the user. For example, if the filler is tobacco containing nicotine, the user may feel calm, relaxed, and experience a tingling sensation. If the filler is cannabis containing THC, the user may feel a sense of euphoria, well-being, relaxed, and jovial. Other sensations associated with THC includes increased awareness of sensations and creativity.

Referring back to FIG. 2A, the cigarette 100 also includes a capsule 130 embedded within the filler 140 and a second wrapper 120 that is located over the first wrapper 110 and at least adjacent (i.e., surrounding) the capsule 130. In one embodiment of the present invention, the capsule 130 contains a liquid that can be released by crushing (or snapping) the capsule 130. As shown in FIG. 2B, this may be accomplished by pressing inward on the second wrapper 120 (e.g., via the thumb and forefinger), thereby crushing or snapping the capsule 130, allowing release of the liquid included therein. An indicium (see, e.g., FIG. 2D at 180) (e.g., company logo, trademark, etc.) may be used to indicate where to press on the second wrapper 120 to crush or snap the capsule 130. The liquid would then coat or cover the surrounding filler, creating a laced version of the filler, referred to herein as the “splash zone.”

For example, assume the filler is cannabis having a first level of THC and the liquid includes (at least in part) a cannabinoid oil having a second level of THC. By crushing the capsule and releasing the liquid, the cannabinoid oil would flow or seep into and over the surrounding cannabis, resulting in a “splash zone” having a higher THC level than that of the cannabis itself. This would allow a user to “boost” the level of THC that is ingested by merely pressing inward on the second wrapper, thereby crushing the capsule and releasing the liquid into the filler. FIG. 2C illustrates the splash zone 150 that is created by pressing inward on the second wrapper. While FIGS. 2A-C provide a cross-section of the cigarette 100, illustrating its contents, FIG. 2D provides a planer view, illustrating the cigarette as it may look to the user prior to use.

It should be appreciated that the present invention is not limited to the embodiment depicted in FIGS. 2A-D. Other exemplary embodiments are discussed herein (see below). As discussed above, the present invention is not limited to any particular type of first wrapper. While the first wrapper may be a single rolling paper (e.g., Zig-Zag™, which is made from wood pulp, flax, and natural gum Arabic), other wrappers (discussed above) are within the spirit and scope of the present invention. For example, if the cigarette is marketed as all natural and organic, so too may be the wrapper. While different wrappers may have different tradeoffs, the first wrapper should contain (or support) the filler and aid, or at least not inhibit, combustion of the same.

As discussed above, the present invention is also not limited to any particular type of filler. While the filler may be a type of cannabis, other fillers (discussed above) or combinations thereof are within the spirit and scope of the present invention. For example, a cigarette containing tobacco is within the spirit and scope of the present invention. By way of another example, a cigarette containing cannabis, either alone or combined (or laced) with at least one substance (e.g., hashish, cannabinoids, terpenoids, flavonoids, etc.) is also within the spirit and scope of the present invention. By way of another example, a cigarette containing hemp, cloves, etc., is further within the spirit and scope of the present invention.

It should be appreciated that the second wrapper serves a function that is similar to that of the first wrapper, i.e., to contain (or support) the filler, or a portion thereof. In other words, once the liquid is dispersed throughout a portion of the filler, creating a splash zone, the first wrapper, which may be a single rolling paper, may not be sufficient to contain (or support) the same (i.e., the moistened or laced filler). Hence the reason for the second wrapper adjacent (or surrounding) the splash zone. The second wrapper also serves a function that is different from that of the first wrapper. As discussed above, inward pressure may be applied to the second wrapper to crush or snap the capsule. Thus, the second wrapper should be resilient enough to spring substantially back to its original shape (e.g., substantially cylindrical) or close thereto.

Depending on certain factors (i.e., the size of the capsule, the amount of pressure that must be applied to crush or snap the capsule, the amount of fluid inside the capsule, the dispersion rate, the type and thickness of first wrapper, etc.), the second wrapper may be identical to the first wrapper (e.g., both being a single rolling paper, thereby providing a two-rolling-paper thickness around the splash zone, etc.), identical to the first wrapper, but containing additional layers (e.g., the first wrapper being a single rolling paper and the second wrapper being two rolling papers, thereby providing a three-rolling-paper thickness around the splash zone, etc.), or different from the first wrapper (e.g., the first wrapper being a single rolling paper and the second wrapper being a paper (e.g., hemp paper, etc.), leaf, or cardboard that is at least two times thicker than the rolling paper, etc.). Again, while different wrappers may have different tradeoffs, the second wrapper should preferable contain (or support) the splash zone, aid, or at least not inhibit, combustion of the same (unless it is removable, see below), and be somewhat resilient. And while the foregoing factors may dictate a different ratio, a wrapper-thickness, splash zone to non-splash zone ratio of 2:1 or 3:1 is preferred.

With respect to the term “capsule,” it should be appreciated that this term is used herein in its broadest sense to mean any secured substance, regardless of how the substance is secured. For example, as shown in FIG. 4A, the substance may be a liquid 420, which is secured using a gelatinous shell 410 (i.e., a gel cap). As shown in FIG. 4B, it may be secured using a two-part capsule comprising a left half 410A and a right half 410B, which are assembled during the manufacturing process. Depending on how the two halves are constructed and mated together, the weakest part of the capsule, and therefore the first to break upon the application of inward pressure, may be the joint itself, which may cause the liquid therein to be dispersed vertically (i.e., up and down). If this is not desirable (e.g., it creates a splash zone that is too close to the first and/or second wrappers, etc.), then the capsule may be designed to disperse the liquid horizontally (i.e., left and right). As shown in FIG. 4C, this may be accomplished using a capsule that has an upper half 410C and a lower half 410D. Again, depending on how the two halves are constructed and mated together, the weakest part of the capsule, and therefore the first to break upon the application of inward pressure, may be the joint itself, which may cause the liquid therein to be dispersed horizontally.

It should be appreciated that the present invention is not limited to the capsules depicted in FIGS. 4A-C. First, while the substance included therein is preferably a liquid, there are situations where the substance may be a solid. Second, while the shell is preferably construed to break upon the application of pressure, the present invention is not so limited. For example, the shell may be constructed to melt upon the application of heat, or there may be no shell at all (e.g., if the substance is a solid, if the liquid is contained in a sponge-like material, etc.). Third, if the capsule is designed to break, various designs can be used to determine (1) how much pressure is required to break the shell and (2) how the liquid is dispersed.

For example, as shown in FIG. 5A, the capsule (e.g., gel cap) may include a shell 410 having an upward opening 500. As shown in FIG. 5B, liquid 420 may then be added to the shell 410 via the opening 500. A cap 510 may then be used to close (or plug) the opening 500 (see FIG. 5C). The capsule may then be rotated and added to the cigarette so that the capsule is left justified and the cap 510 is facing the filler. In this embodiment, the cap is configured to separate from the capsule (blow-out) upon inward pressure being applied to the shell. Once the cap is gone, the liquid will exit the opening as shown by the arrows in FIG. 5D. It should be appreciated that this is merely an example of a capsule that may be used in the present invention, and other types and constructions of capsules are within the spirit and scope of the present invention.

For example, in one embodiment of the present invention, the shell is constructed using a material that will produce a “snap” sound when it breaks. Not only does this create an auditory experience that a user may like (e.g., find enjoyable, etc.), but it allows a user to know when the shell breaks and fluid is being dispersed (i.e., keep pressing inward until you hear a “snap” sound). For example, the capsule may be constructed using a cellulose-based shell, which may be vegan, organic, etc. Such a shell will “snap” when it is crushed. The shell may also include at least one ingredient typically found in cannabis. For example, the shell (e.g., cellulose-based shell, etc.) may include at least one cannabinoid (e.g., THC, CBD, etc.). By doing this, smoke from the shell itself (either after it is crushed, or in lieu of crushing), assuming the cigarette is smoked into through the shell region (i.e., the shell is smoked), will deliver an increased level of cannabinoids to the user. By way of another example, the shell is constructed (at least primarily) from cannabinoids, or products derived therefrom. For example, “shatter” is a type of cannabis concentrate created by extracting the cannabinoids found in the cannabis plant. The result is a translucent cannabis concentrate that breaks and shatters like glass. Processes for creating shatter may include distillation, winterization, and or de-waxing (e.g., to remove impurities such as plant lipids, waxes, etc.). As in the prior example, smoke from the shell itself (either after it is crushed, or in lieu of crushing) will deliver an increased level of cannabinoids to the user. In other examples, the shell also (or alternatively) includes at least one terpenoid and/or at least one flavonoid.

It should also be appreciated that the liquid inside the capsule (in such embodiments) is not limited to any particular liquid, and may include any fluid, such as liquid nicotine, cannabinoids (or cannabinoid oils) (e.g., tetrahydrocannabinol (THC), cannabidiol (CBD), cannabinol (CBN), cannabigerol (CBG), etc.), terpenoids (or terpenoid oils) (e.g., pinene, myrcene, limonene, caryophyllene, linalool, humulene, ocimene, terpinolene, citrulline, etc.), and/or flavonoids (or flavonoid oils) (e.g., flavonols, such as those naturally found in apples, tomatoes, etc., flavan-3-ols, such as those found in bananas, blueberries, etc., flavones, such as those found in parsley, oranges, etc., flavonones, such as those found in grapefruit, lemons, etc., and anthocyanidins, such as those found in strawberries, cherries, etc.). The capsule may also include other substances, such as propylene glycol, etc., which may function as a diluent for thicker, lower viscosity substances (e.g., cannabinoid oils, etc.). The fluid should preferable increase, alter, or supplement the effects (e.g., the high, etc.), flavor, taste, smell, medicinal value, and/or enjoyability of the cigarette.

While the present invention is not limited to any particular fluid (or for that matter, the use of fluid at all), because we are dealing with a smokable element, the liquid, or properties thereof (e.g., THC, CBD, CBG, terpenoids, flavonoids, etc.) are ingested by inhaling vapors from the splash zone (i.e., liquid-coated filler) and/or smoke from a combustion thereof. In other words, certain liquids will put off vapors once the liquid is exposed to air (hence one reason for encapsulating the liquid until it is ready to be used). For these liquids, the flow of smoke, air, or vapor in the case of an e-cigarette, over the splash zone is sufficient to ingest its properties. For other liquids, ingestion results from smoking, or inhaling the smoke produced during combustion of the splash zone.

It should be appreciated that for some liquid, ingestion is a combination of the two. Thus, by placing the splash zone near the user's mouth, the user will inhale vapors from the splash zone while the user is smoking the filler. These vapors may contain certain terpenoids or flavonoids, thereby enhancing the user's smoking experience. Once the combustion reaches the splash zone, smoke resulting therefrom may contain certain cannabinoids (e.g., THC, CBD, CBG, etc.), thereby enhancing (or boosting) the effects (e.g., the high, medicinal value, etc.) of the cigarette. Thus, a single capsule can be used to provide a two-tier effect. For example, if the capsule includes both cannabinoids and terpenoids, then breaking the capsule will result in the user inhaling vapors from the terpenoids while smoking the cigarette. These vapors are coming off the splash zone even when the splash zone is not being smoked. However, if the user smokes through the splash zone, the user will inhale smoke from the cannabinoids.

While placing the capsule near (or closer to) the user's mouth is preferred, other locations are within the spirit and scope of the present invention. For example, as shown in FIG. 9, the capsule may be place near the distal end of the cigarette, so that the splash zone is smoked first or not at all (if the capsule is not broken before the cigarette is lit). By placing the capsule near the distal end, smoke from the splash zone flows through the remainder of the cigarette, thereby altering the experience of smoking the same. By way of another example, other capsules may be placed throughout the cigarette (see FIG. 11), allowing the user to crush or snap one or more capsules. In this embodiment, the liquid included in each capsule may be the same (allowing the user to control concentration) or different (providing the user with more control over the type of liquid dispersed). For example, one capsule may be more flavor oriented, while another may be more psychoactive oriented, etc. It should be appreciated that the size of the capsule may depend on a thickness of the shell and an amount of liquid included therein. Thus, in certain embodiments, the capsule may be quite large (see, e.g., FIG. 9) (e.g., having a diameter that is over half the diameter of the cigarette, etc.), whereas in other embodiments, the capsule may be quite small (see, e.g., FIG. 10) (e.g., having a diameter that is less than half the diameter of the cigarette, etc.). A smaller diameter (e.g., having a diameter that is less than a quarter of the diameter of the cigarette, etc.) is preferred as it allows air to easily flow through the cigarette prior to the capsule being crushed.

As previously mentioned, a drawback to adding a substance, especially liquid, to the filler portion of the cigarette, is that if the liquid is too thick, or has too high of a viscosity, it will not readily spread (or flow) throughout the filler. Alternatively, if the liquid is too thin, or has too low of a viscosity, it may spread (or flow) to easily, which may inhibit burning of (and/or pulling of air through) the splash zone and/or affect the integrity of the cigarette (e.g., dampening the wrapper, causing the cigarette to fall apart, etc.). For this reason, a liquid that has a medium viscosity (e.g., between 500-5000 cps at 70° F.) is preferred. This can be achieved by mixing a liquid having a low viscosity, such as terpenoid oil, with a liquid having a high viscosity, such as cannabinoid oil, at a ratio of roughly 2:1. This results in a mixture having a viscosity that is not too thick to prevent flow, and not too thin to present the problems described above. It should be appreciated that while a liquid having medium viscosity is preferred, the present invention is not so limited. For example, a capsule containing only cannabinoid oil, only terpenoids, etc., is within the spirit and scope of the present invention. Different viscosities can be addressed by modifying the filler (e.g., type, density, etc.), the second wrapper (e.g., thickness, etc.), the capsule (e.g., location, release rate, etc.), etc.

While viscosity is an important feature, so too is the liquid itself and its effect on the burnability of the cigarette. For example, prior art capsules, which are used in the filter portion of the cigarette, generally include water. This is done for two reasons. First, water (itself) acts as a filter. Thus, by adding water to the filter portion of the cigarette, the filter can better function to remove impurities. Second, water can be used as a diluent (e.g., to dilute other substances that are contained within the capsule). While water may work well in the filter portion of the cigarette, it would not work well in the filler portion of the cigarette. This is because water is not flammable and is instead a fire retardant. In other words, the adding of water to the filler would prevent (or at least hamper) combustion of the same. In contradistinction, terpenoids and cannabinoid oils are flammable and are fire accelerants. Thus, not only are there benefits associated with terpenoids and cannabinoids (or the ingestion thereof), but they actually increase the burnability of the cigarette. This is in stark contrast to prior art capsules, which prevent (or at least hamper) combustion.

With respect to the second wrapper, it should be placed adjacent (e.g., surrounding) the capsule, allowing the wrapper to be squeezed to break the capsule. The second wrapper may also be placed adjacent (e.g., surrounding) the splash zone, allowing the wrapper to support the same. While the second wrapper may have a length that is equal to that of the first wrapper, a shorter second wrapper is preferred, as a thick wrapper is generally not a positive for a cigarette. For this reason, the length of the second wrapper should be as short as possible, while still providing the necessary functionality. While this may result in an increased wrapper thickness around the splash zone, those skilled in the art may find this acceptable, especially since the splash zone may burn hotter than traditional tobacco (especially if it includes cannabinoid oil). In other words, while a thick wrapper is generally not desirable, it may be less noticeable around a splash zone having a higher burn rate.

As shown in FIG. 6, the second wrapper may be slightly longer than the length of the capsule, but shorter than the length of the first wrapper. This can be seen in FIGS. 7A and 7B, which show cross-sections of the cigarette at A and B (see FIG. 6), respectively. While the first wrapper 110 is present in both cross-sections, the second wrapper 120 is only present in cross-section A (i.e., adjacent the capsule). And as shown in FIG. 7A, the second wrapper 120 may have a thickness T2 that is at least twice that of a thickness T1 of the first wrapper 110. This allows the first wrapper 110, which is the only wrapper present at cross-section B (see FIG. 7B), to remain relatively thin, while the second wrapper 120, which may only be present adjacent the capsule (see FIG. 7A), is thicker, and therefore more resilient and supportive. As discussed in greater detail below, the second wrapper may be affixed to the first wrapper or slid over the first wrapper (e.g., by the user, the manufacturer, etc.).

In another embodiment of the present invention, as shown in FIG. 8A, the second wrapper 120, providing resiliency and support, is located inside (or between the inner surfaces of) the first wrapper 110. This would provide the cigarette with the foregoing functionality, while retaining a more traditional outward appearance. As shown in FIG. 8B, a capsule 130 and perhaps a portion of filler 140 may be surrounded by the second wrapper 120, creating a self-contained chamber 830, which can be inserted directly inside the cigarette. In this embodiment, markings (see FIG. 2D) may be placed on the first wrapper, where the capsule is located, providing the user with information on where to squeeze the cigarette to break the capsule. It should be appreciated that the first and second wrappers are preferably cylindrical and may or may not have ends. In other words, while each wrapper may circumferentially surround the filler, it may or may not completely encase the filler (e.g., with ends). Moreover, to the extent that a wrapper has an end, the end may not be straight or perpendicular as shown but may be twisted (see FIG. 1B) or take some other form, especially if the cigarette is hand rolled. The existence and/or shape of the end(s) are true for the “chamber” embodiment (FIG. 8B) as well.

It should be appreciated that the cigarette may include other features found on traditional cigarettes, including a filter and/or tip. For example, as shown FIG. 12, the cigarette may include a tip 160, where the capsule 130 is in the filler, as previously described. The tip 160 is configured for placement in the user's mouth and may be a hardened material (e.g., plastic, carboard, etc.) or a water-resistance coating, such as those used in traditional cigarettes. In the case of the former, the tip may be affixed to the proximal end of the cigarette (e.g., using hot-melt, emulsion-based adhesives, etc.). In the case of the latter, the coating (e.g., polyvinyl alcohol, etc.) may be placed over the proximal end of the first wrapper, or over the second wrapper if it is located over the proximal end of the first wrapper.

As shown in FIG. 13, the cigarette may include a filter 170, where the capsule 130 is in the filler, as previously described. The filter 170 is configured for placement in the user's mouth and may be made from known filtering materials (e.g., cellulose acetate (e.g., made from esterifying cotton, wood pulp, or hemp), etc.), such as those used in traditional cigarettes. In an alternate embodiment, the capsule may be placed within the filter, as shown in FIG. 14. In this embodiment, the capsule 130 would be crushed, resulting in the liquid being dispersed throughout the filter material. Because the filter is not smoked, only vapor from the liquid would be ingested. However, if the capsule 130 was designed to release fluid toward the filler (see, e.g., FIG. 4C, FIG. 5D, etc.), then the capsule 130 could be placed within the filter 170 and still create a splash zone that can be smoked. This may be in place of or in addition to liquid being dispersed into the filter 170. Such an embodiment may still require a second wrapper for containment, but would not require resilience, since the filter 170 is squeezed to break the capsule 130. This would allow the second wrapper to be thinner than previously described, where the thickness depends on the location, size, and nature of the splash zone. In an alternate embodiment, a tip may be affixed to (or placed over) the filter. As before, the tip 160 may be a hardened material affixed to a proximal end of the filter 170 (as shown in FIG. 15), or a water-resistance coating placed over the filter (not shown).

In a second embodiment of the present invention, the cigarette may be both cylindrical and tapered, where the diameter of the cigarette increases from a proximal end to a distal end. This can be seen in FIG. 16, where the cigarette 1500 includes a first wrapper 110, a second wrapper 120, a filler 140, and a capsule 130 embedded within the filler 140. As with the other embodiments, the cigarette 1500 includes a proximal end 104 and a distal end 102. However, in this embodiment, the diameter of the cigarette 1500 increases from the proximal end 104 to the distal end 102. Those skilled in the art will understand that there are certain benefits to this “tapered” shape. For example, by increasing the width of the cigarette 1500 at the distal end 102 and decreasing the width of the cigarette 1500 at the proximal end 104, less filler 140 is tainted by smoke drawn though the cigarette 1500.

FIG. 17 illustrates how the second embodiment would look to the user prior to combustion. Because the second wrapper is tapered, like the cigarette, it may be designed to be slid onto the cigarette. This would allow, for example, the user to slide the second wrapper over the cigarette. As shown in FIG. 18, because the first and second wrappers 110, 120 are tapered, the second wrapper 120 can be slide over the first wrapper 110 to position C, which is where the inner diameters of the second wrapper 120 are substantially equal to the outer diameters of the first wrapper 110. The different diameters of the second wrapper 120 can be seen in FIG. 19, where an inner diameter D1 of a distal end of the second wrapper 120 is larger than an inner diameter D2 of a proximal end of the second wrapper 120. The diameters D1 and D2 are a result of the second wrapper 120 being tapered and prevent the second wrapper 120 from sliding beyond position C on the first wrapper 110. See FIG. 18.

Similar to the way in which the second wrapper can be configured to slide over the first wrapper, the chamber (see FIG. 8B), or the second wrapper thereof, can be configured to slide inside the first wrapper. This can be seen in FIG. 20, where the second wrapper 820 is located inside the first wrapper 110 toward a proximal end 104 of the cigarette 1500. In this embodiment, the capsule 130 may be placed within (or between) the second wrapper 820, allowing the second wrapper 120 (along with the first wrapper) to provide the aforementioned support for the splash zone. It should be appreciated that while the second wrapper is tapered and configured for placement at the proximal end of the cigarette, the present invention is not so limited.

It should be appreciated that the capsule may be supported within the chamber in a number of ways. For example, as shown in FIG. 21A, the capsule may be positioned within filler 140A, which may be different from (or same as) the filler adjacent the distal end of the cigarette (see FIG. 20 at 140). That way the chamber may be manufactured with a first filler (e.g., hemp, low-grade cannabis, etc.) and the cigarette may be manufactured with a second filler (e.g., high-grade cannabis, etc.). As shown in FIG. 22, the result may be a cigarette having a chamber 830 wrapped around a first filler and a capsule, a first wrapper 110 wrapped around the chamber 830 and a second filler, and a tip 170 adjacent the chamber 830. Obviously, other embodiments are within the spirit and scope of the present invention.

By way of another example, the capsule may be positioned within an inner structure 820A having passage ways 820B allowing for the free-flow of air or smoke 820C. In other words, the function of the chamber is not to filter, but to support and create a splash zone once the capsule has been crushed. However, it must also allow for air or smoke to flow therethrough. As shown in FIG. 23, this can be accomplished via a plurality of nested cylinders 820B (or one large spiral, not shown), where the capsule is placed in the center. The cylinders 820B should allow the capsule to be crushed (upon the application of inward pressure) while retaining the chamber's shape (e.g., springing back to a substantially cylindrical shape, etc.). The cylinders 820B (or at least the inner several) may also receive (e.g., absorb, etc.) fluid dispersed from the capsule. If the liquid is a terpenoid or flavonoid, air or smoke flowing through the passage ways laced with fluid will deliver vapor to the user.

As shown in FIG. 24, the inner structure 820C is arranged to form a matrix, where the capsule is placed in the center. FIG. 25 shows another arrangement, where the inner structure 820D is honeycomb-like. Both of these designs would secure the capsule in the center, provide resiliency, provide a splash zone (e.g., the portions of the inner structure adjacent the capsule, the portions of the inner structure adjacent the inner structure adjacent the capsule, etc.), and still allowing for the free-flow of air or smoke. It should be appreciated that the present invention is not limited to the structures shown in FIGS. 23-25, and any design that secures the capsule, is resilient, and provides a plurality of passage ways for the free-flow of air (both before and after the capsule is crushed) is within the spirit and scope of the present invention.

FIG. 26 illustrates how a smokable element is constructed in accordance with one embodiment of the present invention. First, a first wrapper 110 is formed, preferably out of rolling papers. The first wrapper 110 is preferably cylindrical and tapered. A first amount of filler 140A is then placed inside the first wrapper 110, at the bottom (or proximal end) of the first wrapper 110. A stopper 2600 (which may be a flat surface, an inner tip (see FIG. 20), etc.) may be used to prevent the first amount of filler 140A from falling out the bottom (or proximal end) of the first wrapper 110. A capsule 130 is then placed inside the first wrapper 110, on top of the first amount of filler 140A. The capsule 130 is preferably oriented so that the liquid within is expelled in a particular direction(s) once squeezed and centered in the first amount of filler 140A. A second amount of filler 140B is then placed inside the first wrapper 110, preferably filling the gaps between the capsule 130 and the inner surfaces of the first wrapper 110, to the top (or distal end) of the first wrapper 110. A second wrapper 120 can then be slid over the first wrapper 110, as illustrated in FIG. 18. The second wrapper 120 could then be removed prior to smoking, or at least prior to smoking the splash zone.

It should be appreciated that the present invention is not limited to the manner of construction illustrated in FIG. 26. For example, a smokable element where first and/or second wrappers are not tapered, but instead uniform in diameter, is within the spirit and scope of the present invention. Also, a gap may be left between the top (or distal end) of the second amount of filler and the top (or distal end) of the first wrapper. This would allow the top (or distal end) of the first wrapper to be twisted (see, e.g., FIG. 1B), thereby sealing one end of the cigarette and providing a tip that can easily be lit. Finally, the first wrapper may be rolled (or constructed) after materials (e.g., first amount of filler, capsule, and/or second amount of filler) have been placed inside (or on) the first wrapper. Similarly, the second wrapper may be rolled (or placed) onto the first wrapper during the manufacturing process. These and other modification are within the spirit and scope of the present invention.

FIG. 27 illustrates a method for manufacturing a smokable element. In particular, starting at step 2700, a first wrapper is formed at step 2702. At step 2704, a determination is made as to whether a tip and/or filter is to be added to the smokable element. If the answer is YES, the tip and/or filter is affixed to the first wrapper at step 2706. If the answer is NO at step 2704, or after a tip/filter has been affixed at step 2706, a first portion of filler is placed inside the first wrapper at step 2708. A capsule is then placed inside the first wrapper, on the first portion of the filler, at step 2710. At step 2712, a second portion of filler is then placed inside the first wrapper, covering the capsule. The top of the first wrapper is then sealed at step 2714, which may involve twisting the top of the first wrapper. A second wrapper is then formed (or placed) over the first wrapper at step 2016, ending the method at step 2718.

It should be appreciated that the present invention is not limited to the steps recited in FIG. 27, and a method that includes, few, additional, or different steps is within the spirit and scope of the present invention. For example, a method that does not include placing a first portion of filler in the first wrapper (e.g., in cases where the capsule is embedded within the filter, etc.) and/or does not include the step of sealing the top (or distal end) of the first wrapper is within the spirit and scope of the present invention. By way of another example, a method that further includes pressing the filler (first and/or second portions) into the first wrapper and/or performs the “second wrapper” step (i.e., step 2716) before steps 2708, 2710, 2712, or 2714, is also within the spirit and scope of the present invention.

Having thus described several embodiments of a system and method for manufacturing and using a smokable element, it should be apparent to those skilled in the art that certain advantages of the system and method have been achieved.
